Hi, I use DjayPro with my Macbook Air M2 (Tahoe), sometimes with the Spotify app, along with a Denon MC6000MK2 controller. Unfortunately, if Spotify is playing (maybe in the pre-set mode), when I press Play/Cue in DjayPro, the music stops in Spotify too. Does this happen to anyone else? How can I avoid this?

In Spotify a single account is only allowed to play on a single device and a single app at the same time. This is probably causing the issue: When you start, load or cue a song in Djay, it will automatically stop playing in the Spotify app. When you want this to work you might need a Spotify family account, or two Spotify account. Or play from another source, like local files, Apple music, Tidal etc
I thought the same thing, but Djaypro had local tracks loaded, not Spotify tracks. A few weeks ago (I’m not sure exactly) this wasn’t happening. 
Hi @Scoop, @EwoutdeBoer has this mostly right. Spotify only allows one active playback stream per account — start playback anywhere else and the stream transfers, pausing whatever was playing. djay’s Spotify login counts as its own playback session on your Mac, so it’s subject to the same rule.
What I can’t confirm is whether that session should be grabbing the stream while you’re only playing local files. Worth a quick test: log out of Spotify in djay via Library > Log Out of Spotify, then play a local track with the Spotify app running. If Spotify keeps going, we know djay’s Spotify session is the trigger.
Which djay version are you on? You mentioned it wasn’t happening a few weeks back, so that’d be useful to know. Thanks!
Thanks a lot Slack, I’ll try this, I’m using the latest version available in the app store because I always update quickly with every update.
I’ll be back for an update
You’re welcome @Scoop. Sounds good
Here I am, last night I tried and DjayPro worked perfectly without turning off Spotify with the background music, it comes to mind that maybe last time I was really using a Spotify track and therefore stopped the app. 
Thanks anyway for the quick help, I will keep you updated! 
You’re welcome @Scoop. Sounds good!
Hi again @Scoop, it’s been about a week, so I’m guessing this is no longer an issue for you and I’ll consider this topic solved for now. Thanks!
Yes, everything is ok, I was probably wrong 
Great to hear @Scoop! Thanks for the follow up.
Slak, I’m just taking this opportunity to ask you something. Is a MIDI map made on a Mac also compatible on Windows? Are there any problems using OneLibrary export with m4a tracks from iTunes? Thanks.
Hi @Scoop, yes, your MIDI mapping made on macOS will also work on Windows.
Regarding your OneLibrary question. djay reads AAC (M4A/MP4) files normally, and there’s no format restriction documented for OneLibrary export. DRM could be an issue with some M4A tracks though. Tracks added from an Apple Music subscription are protected and won’t load in djay, and iTunes Store purchases from before 2009 can be protected too. Anything bought after 2009 is DRM-free and should work fine. It’s worth checking on the destination player compatibility as well — the CDJ-3000X manual lists .m4a AAC as supported, so if you’re using an XDJ-AZ, OPUS-QUAD or OMNIS-DUO it’s worth confirming in those manuals as well.
Thanks so much!!
I don’t have a Pioneer/AT machine, so I’ll use OneLibrary to export my entire library from Mac to iPad. Is this a good idea, or is it better to use the iCloud method?
Regarding the iTunes tracks, I don’t have any older than 2009, or at least that’s the music I have and use in the evening.
You’re welcome @Scoop. OneLibrary is a good option going from macOS to iOS. Please note that, currently, OneLibrary on iOS is ready-only. So you cannot make changes on iOS and export back to macOS.
Thanks so much for your help! Okay, I just need to transfer my entire library from Mac to iPad, I don’t need to make any changes. Can I do it on OneLibrary?
You’re welcome. Yes you can.
